Working Apps

OBS
Install 
 Just install from the Discover Shop 
 Plugins 
 Pipewire Audio Capture 
 Description 
 Let's you capture any application sound individually 
 Install

Discord
Install 
 You can install from the discovery store but i had varying success with it so instead i used the flathub installation system :
 https://flathub.org/en/apps/com.discordapp.Discord

Vivaldi
Install 
 Vivaldi has issues when installed through the discovery app so i prefer to download the rpm package through their website :
 https://vivaldi.com/fr/download/ 
 It may crash the first time you start it and I have no idea why but it just works afterwards.

Steam
Install 
 So steam was more of an issue because it wasn't showing at first in the app but if you go in discovery and then in settings you will find all the repositories you can download from and some of them are unchecked ( you need to have selected the fact you can use third party repositories during the installation process of Fedora KDE otherwise you might not see this option ) 
 I checked everything that's steam related and also the main rpm Fusion non free otherwise some packages might not download (you probably don't need steam debug and steam source but I'm new to this too :P) 
 
 After that you just need to search steam and you should be able to find it now.

BattleNet
Install 
 So if you want to install battlenet and play anygame on it you will need a layer to do so.
You have multiple solutions : 
 
 Make BattleNet a steam game 
 Lutris 
 Heroic 
 Others that i don't remember 
 
 I tried the steam thing first and it was a great idea ... until it was became a mess depending on if you are on kde or gnome, the version of fedora, ... 
 So i went for Lutris which works very well outside of the fact that the login window can glitch out sometimes but you just need to over with the mouse and stuff should reappear. 
 Lutris 
 Just download lutris from the discovery app, start it, look for battlenet follow the step by step instructions and when you do something like closing the login window and nothing happens just trust the process and wait ... go make a coffee or something i guess.

StreamDeck
Install 
 Just download and follow the opendeck docs it's perfect :

Mix
On Fedora 43 , you don’t install “virtual drivers” the Windows way.
With PipeWire (which Fedora uses by default), you create virtual devices (nodes) such as sinks (outputs) or sources (inputs). These act like Voicemeeter’s virtual inputs/outputs. 
 Below are the main methods — from simple to advanced. 
 
 ✅ Method 1 — Create a Virtual Sink (most common) 
 This creates a virtual output device that applications can send audio to. You can then route it wherever you want. 
 1️⃣ Create the virtual sink 
 pactl load-module module-null-sink sink_name=VirtualSink sink_properties=device.description=VirtualSink
 
 You now have a new output device called VirtualSink . 
 
 2️⃣ Create a virtual microphone (optional) 
 If you want something like a “virtual mic” (for Discord/OBS): 
 pactl load-module module-remap-source master=VirtualSink.monitor source_name=VirtualMic source_properties=device.description=VirtualMic
 
 Now VirtualMic appears as an input device in apps. 
 
 3️⃣ Make it persistent (survive reboot) 
 Create this file: 
 mkdir -p ~/.config/pipewire/pipewire-pulse.conf.d
nano ~/.config/pipewire/pipewire-pulse.conf.d/virtual-devices.conf
 
 Add: 
 context.modules = [
 { name = libpipewire-module-null-audio-sink
 args = {
 node.name = "VirtualSink"
 node.description = "VirtualSink"
 media.class = "Audio/Sink"
 }
 }
]
 
 Then restart PipeWire: 
 systemctl --user restart pipewire pipewire-pulse
 
 
 🎛 Method 2 — Use a Patchbay (Graphical Way) 
 Much easier if you don’t like CLI. 
 🔌 qpwgraph 
 qpwgraph 
 
 
 
 
 Install: 
 sudo dnf install qpwgraph
 
 Launch: 
 qpwgraph
 
 You can visually connect: 
 
 App → Virtual Sink 
 Virtual Sink → Hardware Output 
 Virtual Sink → OBS / Discord 
 
 
 🔌 Helvum (simpler UI) 
 Helvum 
 
 
 
 
 Install: 
 sudo dnf install helvum
 
 Very simple drag-and-connect interface. 
 
 🎚 Method 3 — PulseMeeter (Voicemeeter-style interface) 
 PulseMeeter 
 
 
 
 
 This is the closest conceptual match to Voicemeeter: 
 
 Virtual inputs 
 Virtual outputs 
 Routing matrix 
 Volume control 
 
 Install: 
 sudo dnf install pulsemeter
 
 (If not in repo, use GitHub release or COPR.) 
 
 🧠 What You Usually Want (Common Scenarios) 
 🎮 Route Game + Spotify → One virtual device → Discord 
 Create: 
 
 VirtualSink 
 VirtualMic (monitor of sink) 
 Set Discord mic to VirtualMic 
 Route apps into VirtualSink 
 
 
 🎥 OBS separation (game + mic separate) 
 Create: 
 
 2 null sinks 
 Route each app separately 
 Capture each sink monitor in OBS 
 
 
 🔎 Check Existing Devices 
 pactl list short sinks
pactl list short sources
 
 
 ⚡ Important 
 Because Fedora uses PipeWire , you do not need: 
 
 PulseAudio replacement 
 Kernel drivers 
 External sound drivers 
 
 Virtual devices are just software nodes. 
 
 If you tell me your exact goal (streaming? mixing mic + music? dual PC? Discord routing?), I can give you the exact commands and layout for your setup.
